  • Pivoting electricity-supplying arm 1 is provided, for example, to be mounted on a vertical or other base 2 , preferably fixed, for example on a mast, a pole, a standard lamp, a traffic light, a façade, a wall or other fixed structures.
  • this pivoting electricity-supplying arm 1 has been shown in the different figures as mounted on a pole 3 .
  • base 2 on which pivoting electricity-supplying arm 1 is mounted may be any type and may have additional functions, the person skilled in the art thus being able to plan to mount pivoting arm 1 of the invention on any fixed base 2 appropriate for the situation and for the technical requirements without departing from the general inventive idea.
  • pivoting arm 1 is likely to be bumped violently by the passage of a vehicle or any mobile unit and even of vehicle 4 to be supplied, whether simple or articulated, with train sets or other units. In this case, it therefore must not be torn away accidentally by the passage thereof.

  • This fastening 6 may preferably comprise one or more deflecting means 7 permitting the arm to be deflected from the passage space of the vehicle into a folded-back safety position.
  • the electricity-supplying assembly according to the invention preferably comprises a deflecting hinge 7 that makes it possible to displace electricity-supplying assembly 1 or part thereof into a deflected position.

  • Fastening 6 which comprises deflection means 7 , makes it possible to fold back pivoting electricity-supplying arm 1 , for example by folding back pivotally relative to this pole.
  • This pivoting movement may be assisted by a motor (not shown), which motor may be remote-controlled by a control device.
  • a safety device such as a fusible pin, which normally blocks deflection hinge 7 in the vertical axis and which breaks under shock in order to protect the arm.
  • a resettable device is also possible as a means of blocking by a ball forced by a spring, for example.
